A device for treating hair or scalp, the device comprises a dispenser connected to a cartridge, wherein the cartridge comprises a formulation; a plurality of tips, wherein the tips have at least one opening to dispense the formulation; and a controller that controls the amount of formulation that is dispensed from the tips.

In one aspect, devices for light treatment of skin are described herein. A device described herein, in some embodiments, comprises an interior compartment having a proximal end and a distal end, and an optical aperture disposed at the distal end. The device also comprises a laser or BBL source that produces a laser or BBL beam. The laser or BBL beam has a first optical path within the interior compartment, between the proximal end and the distal end. Additionally, the first optical path exits the interior compartment through the optical aperture. The device further comprises a camera that receives light from the aperture. The light received from the aperture has a second optical path within the interior compartment. Further, a selectively reflective optical element is disposed in the first and second optical paths. The selectively reflective optical element generally transmits the laser or BBL beam but generally reflects at least a portion of the light from the aperture toward the camera.

The present invention relates to a light emitting device for providing dermatological treatment. The present invention comprises a housing structure for housing a light emitting source, a fan and a duct. The light emitting source is arranged to emit light energy to external of the device and the fan is configured for directing air heated by operation of the light emitting source into the duct. The duct is arranged to direct heated air in an airstream pathway from an outlet port of a distal end of the duct and through an aperture in the housing structure where the housing structure and the duct are relatively arranged such that no part of the housing structure extends into the air stream pathway in order to minimise heat exchange from the heated air to the housing structure.

The present invention refers to a skin or hair treatment device for emitting intense light radiation with an integrated sensor. The device has a housing; a treatment light source, wherein the treatment light source comprises an array of a plurality of light emitting elements arranged on a substrate; a sensor system, the sensor system has at least one sensing light source for emitting sensing light and at least one light sensor for detecting the sensing light, wherein the at least one sensing light source and the at least one light sensor are directed towards a device treatment window; and a control circuit having a processor.

Provided is a region division method for laser treatment, and a laser treatment method and apparatus using the same. The region division method for laser treatment according to the present invention divides an area of an object to be treated by laser irradiation into a plurality of treatment regions and includes constructing a three-dimensional image of the object; using the three-dimensional image to obtain a normal vector for each of a plurality of points located on a surface of the object; dividing the points on the surface of the object into one or more groups based on a similarity between the obtained normal vectors; and generating a closed curve including at least some of points grouped into the same group to set a treatment region.

A cosmetic method of treating skin tissue with a source of treatment light includes providing a source of treatment light along an optical axis; providing one or more sources of illumination light along the optical axis; providing one or more sensors along the optical axis; providing a programmable controller, the programmable controller controlling the activation of the source of illumination light and the source of treatment light. The method includes the steps of: the controller activating the one or more sources of illumination light and directing it to the skin tissue, the one or more sensors measuring the light reflected from the skin tissue and transmitting information sensed of measured light to the programmable controller; the programmable controller processing the measured light received from the output of the one or more sensors and providing a treatment light regimen; the programmable controller activating the source of treatment light according to the treatment regimen to the skin tissue; and, treating the skin tissue.

A pet care device may include a removable or swappable care tool mounted on a head. The head may include a sterilizer and a sensor to determine what kind of care tool is mounted. A controller may identify the type of care tool mounted on the head based on a sensing value of the sensor and control the sterilizer based on the identified care tool.

A wearable head article for controlling light incident on the skin, including a filter layer for allowing light to pass through over a treatment area of the head, wherein the filer layer includes material that controls the wavelengths that pass through, and a protective layer for reducing skin exposure to at least one of harmful light and non-beneficial light.

Modulated light therapy devices for treatment of dermatological disorders of the scalp are provided. An exemplary device includes a flexible printed circuit board (FPCB) supporting at least one light emitting device having an emitter height. The FPCB includes multiple interconnected panels and bending regions defined in and between at least some of the interconnected panels as to allow the FPCB to be configured in a concave shape to cover at least a portion of a cranial vertex of the patient. At least one light-transmissive layer proximate to the FPCB is configured to transmit (e.g., incoherent) light emissions generated by at least one light emitting device. At least one standoff is configured to be arranged between the FPCB and the scalp of the patient, wherein the at least one standoff includes a standoff height that exceeds the emitter height.

A pulsed laser skin treatment device is for laser induced optical breakdown of hair or skin tissue. A feedback system is used for detecting a feedback system based on light and/or sound/and/or contact force or pressure. The feedback signal is used to determine whether a pulse was in the tissue or outside the tissue. With these data an effectiveness of the treatment can be determined which can be provided to a user.
